OWC Mercury Rack Pro Chapter 1 - Introduction
1.5.2 Fan Alarm Mute Button
To adjust your RAID settings, there are 3 switches on the back of the OWC Mercury
Rack Pro.
Use the silkscreened settings as a guide when adjusting the switches to the desired
RAID setting. Proceed to section “1.6 RAID Settings” for instructions on changing the
RAID levels on the OWC Mercury Rack Pro.
1.6 RAID Settings
1.6.1 Changing the RAID Mode
IMPORTANT NOTE: Drives of identical model are required for all RAID types other
than Clear & JBOD (Independent Drive) Mode and JBOD (SPAN) “Combine” Mode.
IMPORTANT NOTE: Changing the RAID setup will require you to reformat the drives.
Reformatting deletes all of the existing data on the drives!
Make sure that you have backed up your data before proceeding!
To switch or clear RAID modes, follow these steps:
In the event one of the fans within the OWC Mercury Rack Pro fails, an alarm will
sound. The “Fan Alarm Mute” button located on the rear panel of the unit, will mute
the alarm. It is recommended to replace the failed fan as soon as possible in order to
adequately cool the unit, prevent damage to components, and avoid data loss.
1.5.3 RAID Selector Switches
!
➀ With the OWC Mercury Rack Pro turned OFF, adjust the switches on the back of the
unit to the desired setting (either to “Clear RAID” mode or to a RAID level).
➁ While holding down the SET button, power ON the OWC Mercury Rack Pro. Keep
holding the SET button until you hear a full beep (you may hear shorter chirps or
beeps while the unit is setting itself into the RAID mode). The lights on the Rack Pro
will also ash during this process and will stop ashing when complete.
➂ The OWC Mercury Rack Pro is now set to the newly selected mode. If the Rack Pro
has just been set to “Clear RAID” mode, you can now repeat steps ➀ and ➁ to apply a
RAID setting. If the Rack Pro has just been set to a RAID mode, it is now ready to be
formatted. Instructions for formatting can be found in Chapter 3 of this manual.
IMPORTANT NOTE: Changing the RAID settings requires you to set the
Rack Pro to “Clear RAID” mode between each mode change.
